Byron from injecta told me that you can use the cheyenne flex grip with the vice model flite but you have to have the flex bars from the combo flite because they are longer than the flex bars that come with the vice model flites. He said that if you have the injecta grip that the flex bars that come with the vice model work perfect together. The flex grip comes with a rigid bar with a loop. If your using a grip with no adjustment then the ridged bar needs to be 73 mm long and with adjustable grip it needs to be 86 mm long. Hope this helps.
